Re: [802.3_EPOC] Continuing work on EPOC objectives - OBJECTIVE 4
Kevin,
The wording "baseline plant conditions" is still there.
I believe if we specify what these " baseline plant conditions" are, we do
not need to change the wording in Objective 4 at all.
Typically, we define some parameters of the said baseline plant, even if the
parameters include distance, split count and just generic plant type (single
mode fiber for EPON). For EPoC, it might be enough to define e.g. maximum
loss at specific frequency component or cable type to be used as baseline.
We need some performance markers to measure the future proposals for PMDs,
setting the expectation of EPoC performance.

Another important topic is OBJECTIVE 4.
We have general agreement on the data rate and bandwidth and concept of
scalability (up and down). However, the discussions so far have not settled
on how to set this objective without specifying the specific channel
characteristics, leaving that open for further work in the TF.
My concern with the text, as currently written, is that it requires some
explanation for those that haven't been in the conversation. This held true
during the last conference call and in most every discussion I've had about
this. I would like to make the objective a little more obvious in its
meaning.
Consider this a solicitation for a better statement of the objective.
4. Provide at least one physical layer specification that is capable of
operating at :
A baseline data rate of at least 1 Gbps at the PHY service interface when
transmitting in 120 MHz, or less, of assigned spectrum under baseline plant
conditions; data rates lower than the baseline rate when transmitting in
less than
120 MHz of assigned spectrum or when plant conditions prevent a higher data
rate; data rates higher than the baseline rate and up to 10 Gbps when
transmitting in more than 120 MHz of assigned spectrum or when plant
conditions support a higher data rate;
